micrometer-metrics/micrometer v1.18.0-RC2

1.18.0-RC2

on GitHub

⚠️ Noteworthy

• Atlas FunctionTimer behavior change: AtlasMeterRegistry now publishes FunctionTimer statistics (count and totalTime) as per-second rates instead of gauges (#8108). With the default 1-minute step, published values will be ~60x lower than before; any dashboard queries or alert rules dividing by 60 should be updated. See the 1.18 Migration Guide for details.
